Custom Rhinestone — Nickel-Free Alloy with Ultrasonic Welding
We supply rhinestone to garment factories and brands, built in Nickel-Free Alloy with ultrasonic welding for denim and workwear programmes. On a trim like this the specification that decides the outcome is glue activation window on a hot-fix stone, so that is agreed in writing before bulk — not discovered when the first carton is opened on the line. Programmes start at 500 pieces per style per finish.
The failures here are predictable: minimum order quantities far above what a growing brand can absorb, or colour drift between the approved sample and the bulk trim. We lock material, finish, dimension and tolerance before bulk, and prepare GB 18401 safety classification with GB/T 29862 fibre labelling so the shipment clears instead of sitting at port while your selling season passes.

Where it is used
- Denim and workwear — hard-wearing finishes that survive industrial washing
- Outerwear and tailoring — matched to the shell fabric so it drapes with the garment
- Childrenswear and schoolwear — tested to the destination's safety standard
- Bridal and eveningwear — small runs with hand-finished detail
- Uniform and corporate programmes — repeatable spec held on file for reorders

Packing, testing and delivery
Trims are packed to the ratio you specify — by size, by colour or by garment set — with barcodes applied where the line needs them. Test reports for colour fastness to washing, rubbing and light are prepared for the destination market. We ship to Shanghai or Shenzhen with the commercial invoice, packing list and certificate of origin, and hold the approved reference so reorders reproduce the same material, the same finish and the same glue activation window on a hot-fix stone.
FAQ
What packing options are available?
Bulk packed, carded, or packed to your own size and design ratio with barcodes applied.
How do you control colour on reorders?
The approved reference and the bulk standard are retained, and every reorder is checked against them before shipment.
Which compliance documents do you provide?
We prepare colour fastness to washing, rubbing and light and the supporting test reports for the destination market.
Can you match a reference sample?
Yes. Send the trim and we match material, finish and shade, then confirm on a pre-production sample before bulk.
